Vitamin C Brightening Serum
Vitamin C Brightening Serum
A cold-process, manufacture-ready brightening serum built around Stay-C 50 (a stable, gentle Vitamin C derivative), Camu Camu fruit extract, and White Willow Bark — a formula designed to deliver visible brightening and clarity while staying simple enough to produce without heat-phase manufacturing.
You Own This Formula
When you purchase this formula, the intellectual property is yours. Unlike most private-label or white-label manufacturing relationships — where the manufacturer holds the formula and you're locked into using them — you can take this formula to any GMP-certified manufacturer, anywhere in the world, at any stage of your brand's growth.
This means if your manufacturer changes their pricing, minimum order quantities, or can no longer produce your product, your brand isn't at risk. You're never dependent on one supplier to keep making the product your customers know and trust. Owning your formula outright is rare — and normally an expensive, custom development process. Here, it's built in.
Key Ingredients & Benefits
- Stay-C 50 (Sodium Ascorbyl Phosphate) — a stable, water-soluble Vitamin C derivative that converts to active ascorbic acid in the skin, delivering brightening benefits without the irritation and instability associated with pure L-ascorbic acid.
- Myrciaria Dubia (Camu Camu) Fruit Extract — one of the richest natural plant sources of Vitamin C, boosting the formula's overall antioxidant and brightening profile.
- White Willow Bark Extract — naturally rich in salicin, offering gentle water-exfoliating and clarifying properties that support a brighter, more even-looking complexion.
- Chrysanthemum Indicum Flower Extract — a traditional botanical antioxidant that helps protect skin from environmental stressors.
- Oatsilk — soothes and supports the skin barrier, balancing the brightening actives so the formula stays comfortable on skin.
- Orange Oil & Litsea — a light, natural citrus fragrance that reinforces the fresh, brightening positioning of the serum.
Texture & What to Expect
A lightweight, fast-absorbing serum with a fresh citrus scent and no sticky residue — layers cleanly under moisturiser or makeup. Stay-C 50 and Camu Camu work together for a brightened, more even-looking complexion, while White Willow Bark supports gentle clarity over consistent use.
Why This Formula
Developed by a qualified cosmetic chemist with hands-on formulation and manufacturing experience, built on proven, widely-used actives with published efficacy data — not assembled from generic templates.
Building a formula like this from scratch — sourcing the right actives, balancing percentages, testing phase compatibility, and writing a manufacture-ready process — typically takes a qualified chemist many hours of dedicated work, and commissioning custom formulation development independently can cost $2,500 or more. This formula gives you that same level of expertise, ready to take straight to your manufacturer, at a fraction of the cost and time.
Claims Substantiation
- Stay-C 50 (Sodium Ascorbyl Phosphate) — a well-established, stable Vitamin C derivative with published data supporting brightening and antioxidant benefits, widely used as a gentler alternative to L-ascorbic acid.
- Myrciaria Dubia (Camu Camu) — recognised as one of the highest natural plant sources of Vitamin C, supporting the formula's antioxidant claims.
- White Willow Bark Extract — naturally contains salicin, associated with gentle exfoliating and clarifying properties in published ingredient literature.
This formula is built on proven, widely-used actives with established efficacy data — giving you a credible, science-backed foundation to bring to your manufacturer. As with any new formulation, we recommend Preservative Efficacy Testing (PET) and stability testing on your specific production batch — a standard step every brand takes before commercial launch.
This Formula Includes
- Full INCI ingredient list, in percentage order
- Exact percentages and phase breakdown
- Step-by-step cold-process manufacturing method

Ingredients are globally available — no region-restricted actives — so you can take this straight to any GMP-certified manufacturer, anywhere, and start production.
